Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an opening/closing device for sliding doors such as furniture doors and windows, and according to this opening/closing device, the doors are aligned with each other in a closed state. However, when opened, the doors are placed in two different planes due to two perpendicular relative movements.

PRIOR ART AND ITS PROBLEMS It is known for "r-pulling" doors of furniture in which the opening and closing movements allow the door to slide along parallel guides. The doors are therefore always out of alignment with each other and are movable in two different planes.

This results in poor sealing against dust and is also aesthetically unappealing.

(Means for Solving the Problems and Their Effects) By employing the present invention, the furniture sliding doors are aligned in the same plane when in the closed position, so that they present a substantially uniform surface and have a sealing property. This substantially reduces or prevents dust from entering the interior space of the furniture. This is achieved by means of a guiding mechanism for the door. With this guiding mechanism, when the door moves from the closed position to the open position and vice versa, it first moves in a direction perpendicular to the front of the furniture and then in parallel, so that the door can move from the closed position to the open position and vice versa. When in the open position, they overlap, and when in the closed position, they are aligned.

The sliding movement of the door parallel to the front of the furniture is ensured by two pairs of rollers and an upper guide, while the perpendicular movement is facilitated by two other pairs of guide rollers, a system of sheaves and cables, and an upper guide. .

Other aspects of the invention will become apparent from the disclosure below. Furthermore, this summary of the invention is not intended to be limiting in any way.

(Example) Hereinafter, an example of the present invention applied to a furniture member having two doors will be described with reference to the accompanying drawings.

With the device of the invention, a piece of furniture with a large number of sliding doors can simply actuate any zone of the door that it wishes to open.
They can be opened to move from the aligned closed position to the open overlapping position. This also applies to the stage of closing the door.

As shown in the drawings, the schematically illustrated door compartment 1 comprises several doors, of which two doors 2, 3 are shown.

At the top of each door 2, 3 there is a sliding member or channel 4 of U-shaped cross-section, which is engaged by a roller 5 attached to an extension guide 6, which is connected to the door pocket 1.
It has a fixed part 6a that is integral with the structure of , and a movable part 6b that is slidable along the fixed part and supports the roller 5.

Combined with the lower part of the doors 2, 3, two side trolleys 7 are provided, each trolley 7 moving along a guide member 9 integral with the door compartment structure corresponding to both edges of each door. It holds a pair of grooved rollers 8.

The trolley 7 holds a sliding member 10 of U-shaped cross section, on which is mounted a roller 11 with a horizontal axis and a roller 12 with a vertical axis, these rollers being shown in FIG. 6.11.14. As shown, it is rotatably attached to the lower member 13 of the door. The entire weight of the door 3 can be loaded onto the sliding member 10 via said roller 11 with a horizontal axis.

The lower part 13 of the door also carries two grooved rollers 14. The entire door pocket is provided with a track 15 extending over the entire length of the door pocket front, or at least over a part of the door pocket 1, on which the door slides.

As shown in FIG. 7, when the roller 11 rests on the slide member 10, the track 15 is separated from the groove of the grooved roller 14 by a distance +1h'', so that the grooved roller 14
side flanges 14a (FIG. 14) can pass across the track itself.

A cover member 16 is provided at the front part of the track 15 (sixth
7), the cover member 16 is attached to the track 15 by a snap-on system or the like.

As can be seen in FIG. 6.7.14, the pin 17, which engages in the slot 18 of the rotary roller 19, is connected to the movable part 6b of the slide guide 6. The roller 9 supports a non-stretchable and flexible cable 20 which is wrapped around a lower roller 21. Said lower roller 21 is suitably connected by means of a tubular transmission shaft 22 to two arms 23 , the ends of which are located near the side edges of the door 3 and which engage in link slots 24 of each trolley 7 . Has a pin.

In this way, the translational movements of the two trolleys 7 and the extension guide 6 are tightly coupled, so that the door 3 is always maintained in a plane parallel to the plane in the closed position of the door 3 during movement.

On the opposite side of the roller lla, a descending slope 10a is provided at the end of the slide member 10 facing the translational side of the door 3.
(FIG. 11), the amount of descent of the slope 10a is greater than the above-mentioned value II h II, and the slope 10a is moved toward the end of the slide member 10 at a predetermined position opposite to the opposing roller llb at the opposite end of the slide member 10. It has a slope 10b that rises (see also FIG. 14).

In this case, roller llb is mounted at a higher level than roller Ila.

If translational movement is desired in both directions, ramps 10a should be provided at both ends of the sliding member 10 and extension guides 6 should be provided on both sides of the door.

The slide member 10 has a movable pin 25.
is held in the raised position by cam means or the like associated with the rollers 11 when the door is in the closed position. Also, the door is trolley 7
It can be moved forward on top and then lowered as it is moved in lateral translation.

Block 26 in the forward position of the door in relation to the moving pin 25
, said block 26 having a slot for receiving said pin 25 when said pin is in the lowered position;
This prevents the trolley 7 from moving in the opposite direction when the door is translated laterally.

In the embodiment illustrated in Figures 1 to 5, a piece of furniture has been shown with two doors, but it is possible to open either of these doors relative to the other.

In particular, in Figure 1.2.3, the left-hand door 2, which in the closed position is aligned with the right-hand door 3 (Fig. 1), begins to move in a direction perpendicular to the outer surface (Fig. 2), and this movement At the end of the movement, the movement is continued parallel to the outer surface and in the alignment direction of the doors (FIG. 3), and entry into the interior of the furniture 1 becomes free at the left part of the front of the furniture.

In Figures 4 and 5, the opening/closing operation of the right door 3 is performed by moving this door to the left, and the right door 3 is moved to the left aII door 2 by an action corresponding to that shown in Figures 1 to 3. It is brought to a position that overlaps with the .

6 and 7 especially show the upper rotating roller 19 and the lower roller 21.
A connection is shown made by a non-stretchable and flexible cable 20 between the door and the door, which connection keeps the door always parallel to the vertical front surface of the furniture.

The movement of the door outward from the furniture is further facilitated by moving the two doors 2 and 3 (No. 8.9
．． A slide member 10 with a U-shaped cross section is secured by an extended upper guide 6 disposed in the middle of FIG.
It is secured by two side trolleys 7 connected to each other by.

The movement of the door parallel to the front side of the door pocket 1 is ensured in the upper part by a guide consisting of a roller 5 with a vertical axis and a U-shaped slide member 4 (channel 4), and in the lower part of the door pocket 1 with a horizontal axis. The holding is secured by two pairs of rollers 11, 14, each running on a slide member 10 and a track 15 and guided by three rollers 12 with vertical axes, as shown in the plane of FIG. 11.12.13. .

Referring to Figures 6 and 7, the various components of the device vary from the aligned door position (Figure 6) to the stacked door position (Figure 7).
In other words, the movement and rotation that the door undergoes during the transition process from the closed position to the open position can be seen.

In particular, in the closed position (FIG. 6), the entire weight of the door 3 is supported on the sliding member 10 via the lower member 13 and the pairs of rollers 11.

This weight load distribution is not subject to fluctuations during the opening and closing phases of the door perpendicular to the front of the furniture.

On the other hand, when the door moves parallel to the front of the furniture,
The weight of the door is gradually transferred from the sliding member 10 to the track 15.

Such a weight shift is caused by roller 1 during the downward movement.
1 by engaging with a slope formed at the end of the slide member 10. The rollers 11 are mechanically connected to the grooved rollers 14 via the lower member 13, which connects them to the door, so that each vertical movement of the rollers 11 is caused by the movement of the grooved rollers 14. This is done by a corresponding vertical movement. Therefore, while the door is moved open parallel to the front surface of the furniture, the roller 11 is gradually lowered by the slope of the end of the slide member 10. This causes the grooved roller 14 to be lowered uniformly until it comes into contact with the track 15, so that the weight of the door is transferred from the slide member 10 to the track 15.

The reverse process occurs during the closing phase of the door along a plane parallel to the front of the furniture.

The weight of the door is transferred from the track 15 to the slide member 10 and during this movement the roller is forced upward by the end slope of the slide member 10, which causes the grooved roller 14 to move up.
will rise uniformly with respect to orbit 15.

The movement in which the door re-enters the front of furniture 1 in a direction perpendicular to it is as follows:
The weight is transferred from the track 15 to the slide member 10, i.e. to the trolley 7 and ultimately to the rollers 8 running on the guide 9, and the grooved roller 14 leaves the track 15 and the grooved roller 14 moves out of the track 15 during the re-entry phase. 14 and the avoidance of friction between the track 15.

6 and 7, a non-stretchable and flexible cable 20
Note how the rollers 19, 21 are prevented from rotating and moving out of the door. That is,
In the upper part, this is done by a pin 17 fixed to the movable part 6b of the guide 6. A vertical shaft of a roller 5 running along the slide member 4 is attached to the end of the guide 6. In the lower part, the arm 23 is used. Said arm 23 is suitably connected to the transmission shaft 2 engaged with an interference fit in the mounting of the roller 21 (Fig. 11.12.13).
The movement is transmitted to the two side trolleys 7 supported by the aforementioned pairs of grooved rollers 8 running in the guide member 9;
is transmitted to the door via the sliding member 10 that connects the door.

A roller 11 with a horizontal axis and a roller 12 with a vertical axis lean against the slide member 10, and these rollers 11,
12 is integrally connected to the door by a lower member 13.

As described above, the track 15 and the grooved roller 14 are in operation only when the door is opened or closed in a plane parallel to the front surface of the furniture. 6 and 7 show a cover member 16 for the lower mechanism attached to the track 15 by a snap-on system and a movable pin 25 for locking the trolley 7 in the open position of the door.
shows. Said moving pin 25 can be driven by a cam or the like supported by the lower member 13, and this drive causes the sliding member 10 to move during all movements of the door parallel to the front of the furniture.
The group of trolleys 7 equipped with the above-mentioned movable pins 25 are always maintained in a locked state by the movable pins 25. When the door is in a position where it can be moved rearwardly at right angles to the front of the furniture, the cam can act on the moving pin 25 to disengage the pin 25 from the block 26 attached to the track 15 in a reverse stroke. That is, the connection of the transfer pin 25 to the block 26 takes place during the opening phase of the door, while the cam attached to the lower member 13 is moved from its initial exit position in a direction perpendicular to the front surface of the furniture.

In Figures 8 to 10, the right side door 3 moves from the closed position (Figure 8) in a direction perpendicular to the front of the furniture (Figure 9), and then moves to the open position (Figure 9) along a plane parallel to the front of the furniture. Figure 10)
You can see how the upper mechanism of the sliding door works during the process of moving to.

In particular, in FIG. 9, the movable part 6b of the guide 6 is connected by a pin 17 to a rotating roller 19 in the first opening phase perpendicular to the front surface of the furniture, moving the door 3 parallel to and away from the plane of the door 2. of the guide 6 by bringing it into a plane that does not coincide with that of the guide 6 and allowing the roller 5 with its vertical axis to slide freely along the slide member 4, thereby producing an opening phase (FIG. 10) parallel to the front surface of the furniture. The movement of the movable part 6b is clearly shown.

It is clear that a symmetrical movement with the upper mechanism takes place during the opening phase of the left-hand door 2. 11 to 13 show the lower mechanism of the sliding door at the same stage of movement of the right door 3 as shown in FIGS. 8 to 10 for the upper mechanism.

In particular, FIG. 12 clearly shows the movement undergone by the sliding member 10, which is connected to the lower roller 21 via the transmission shaft 22 and the side trolley 7, which is supported and guided by the grooved roller 8.

In this way, the movement perpendicular to the front of the furniture makes it possible to open the door parallel to the front of the furniture (Fig. 13),
The two doors are now in parallel planes and no longer aligned with each other.

In this way, initially the roller 1 placed on the slide member 10
The weight of the door supported by 1 is transferred to the grooved roller 14 acting on the track 15, in this case the grooved roller 1
4 is a roller 12 with a vertical axis and a grooved roller in this movement parallel to the front of the furniture, controlled by the end slopes 10a, 10b of the sliding member 10 (shown by hatching in FIG. 11.12.13). 14.

From FIG. 13 it can be seen how the movement of the left roller 11 releases the pin 25 and thereby locks the slide 10.

A movement symmetrical to the lower mechanism takes place during the closing phase of the door 3. That is, the weight of the door, which is initially supported by the grooved rollers 14 mounted on the track 15, is gradually transferred to the rollers 11 acting on the slide member 10 under the control of the end slope zones of the slide member 10. , the inclined zone must re-raise the roller 11 during the closing phase to relieve weight from the grooved roller 14.

When the door returns to the position shown in FIG. 12, the pin 25 is disengaged by the cam of the roller 11 and the closing phase of the door 3 can be completed with a movement perpendicular to the front of the door compartment.

The structural features described and illustrated with respect to the accompanying drawings may reveal or suggest various forms, modifications, and alterations without changing the essential characteristics of the invention and without departing from the scope of the patent. .

(Effects of the Invention) By employing the device of the present invention, the doors, which are parts of furniture, can be maintained in a perfectly aligned state when in the closed position, and by moving either one of the doors, the opposite furniture can be opened. This gives you the advantage of being able to open up more space.
